## Overview

Node.js versions 9.7.0 and later and 10.x are vulnerable and the severity is MEDIUM. A bug introduced in 9.7.0 increases the memory consumed when reading from the network into JavaScript using the net.Socket object directly as a stream. An attacker could use this cause a denial of service by sending tiny chunks of data in short succession. This vulnerability was restored by reverting to the prior behaviour.

## Affected

- `node.js >= 9.7.0, < 9.11.2`
- `node.js >= 10.0.0, < 10.4.1`

## Remediation

Upgrade past the affected range:

- `node.js 10.4.1`
